Hi sifus, any DIY'er know any ways to fix loose screw holes on Fire-rated door? My door has an auto closer but the screw became too loose (screw thread no longer attached to the door)

I tried to find those (plaster?) wall plug to maybe screw on? but it doesnt fit (not without drilling through the door).

I'm looking at glue/silicone (home repair) to fill the hole/let cure and try re-screwing in but I haven't try yet cause not sure if it can hold (the fire door is quite heavy)



TLDR: need to screw auto closer to fire door but screw hole too loose, looking for ways to repair.

Thanks in advance
